This achievement is a reference to Team Fortress 2's Meet the Spy video as an introduction to the class 'Spy', who could disguise as enemy players, but also instant kill via backstab and disable buildings (which aren't things the Changeling is capable of).

The easiest way to do this is play as zerg vs a friend playing as protoss. Also possible is playing zerg with a protoss ally; the ally leaves the game and one can use his gateway to make a zealot. Alternatively, play against a easy or very easy protoss AI. Destroy all of the opponent's buildings except one, without hurting the probes. Use an infestor to infest a probe, and use it to build a nexus (and a pylon if there's time enough). From this nexus, build a probe, and warp in a pylon, then a gateway. Then you can create a zealot.
